Actually, no. Here (DE), photographers are allowed to take your picture in public if you are not the main component of that picture (with a few extra exceptions). And that’s just for picture taking. For recording (either video or sound), you need to put up signs on private property and you are not allowed to constantly record public places anyways. So, yes, you can have an expectation of privacy in any public place in the meaning of not being covertly recorded and photographed.
